RUSSEL H. BREMER, NEW YORK, N. Y.

REFRIGERATOR.

Application filed September 6, 1919.

To alt whom it may concern Be it known that I RUSSEL il. BREMER acitizen of the United States, residing at New York city and State of NewYork, have invented new and useful Improvements in Refrigerators, ofwhich the following is a specification.

This invention relates to refrigerators and has for its object theprovision of a refrigerator in which the refrigerating action isaccomplished by evaporation of water disposed within the device, thedevice being molded from extremely porous material whereby to facilitateevaporation.

An important object is the provision of a device of this character whichis provided at its upper portion with oppositely disposed controllableventilators whereby the evaporating action may be hastened.

Another and more' specific object is the provision of a refrigerator ofthis character which is provided in its lower portion with a watercontaining pan into which extend wicks disposed within grooves in thewalls of the device. y

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture7 highly eflicientand inexpensive in use as eliminating the necessity for ice, durable andsanitary in service, and a general improvement in the art.

With the above and other objects and advantages in view7 the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawing inwhich- Figure 1 is a front elevation of my refrigerator7 Fig. 2 is aside elevation,

Fig. 3 is a cross sectional view on the line 3 3 of Fig. 1, and

Fig. 4L is a vertical sectional view on the line 4--4 of Fig. 2.

Referring more particularly to the draW- ings, the numeral 10 designatesthe body of the refrigerator which is molded from eX- tremely porousmaterial such as plaster of- Paris cement or various clay substancesnoted fortheir extreme porosity. This body is formed with its frontopen, as shown, and all the other faces closed except the sides 11 whichare provided with cylindrical holes 12 within which are securedventilators in- Speeication of Letters Patent.

dicated broadly by the numeral 13. These ventilators will be hereinafterdescribed more in detail.

` Hinged upon the front of the body, as shown at 14, is a door 15 whichis preferably hollow and filled with any suitable well known heatinsulating material indicated at 16. This door is so constructed as tohave flanges 17 overhanging the edges of the open front. A suitablecatch mechanism 18 is provided for holding the door normally closed. i

Formed upon the inner faces of the sides and back walls of the body 10are vertically extending grooves 19 which extend to points substantiallyon a line with the-bottoms of the ventilator holes 12. The innerportions of these grooves 19 are formed wider than their entrances andare adapted to have dis posed therein wicks 20 which will beconsequently retained in position. Disposed within the bottom portion ofthe body 10 is a pan 21 containing water to which is preferably added asmall amount of ammonium chlorid. This pan is provided adjacent theupper edges of its side and back walls with recesses 22 which registerwith the lower ends of the grooves Y19 and through which the wicks 2Oextend into the water contained Within the pan. A cover plate 23 isseated upon the pan 21 and is preferably flush with the lower edge ofthe door opening and this cover forms a closure for the pan. This coverplate is provided preferably adjacent its corners, with holes 24 throughwhich the operator may insert his fingers for lifting it out when 1t isdesired to replenish the water within the pan.

Each ventilator member 13 comprises a cylindrical casing 25 securedwithin the opening 12 and having a fiange 26 bearing against the wall.The outer end of each cylindrical casing 25 is closed except for aplurality of perforations 27. Rotatably mounted upon the closed end ofthe casing is a plate 28 carrying an operating handle 29 and providedwith a segmental openin 30 adapted to uncover a desired number o saidperforations 27.

In the use of the device it will be seen that water disposed within thepan 21 will be drawn through the wicks 20 through natural capillaryaction and will be thus supplied to the porous body.y Evaporation willof course occur which will result in drawing Yfi the heat from theVinterior of the body, thus providing an eiiicient refrigerating action.

y By regulating the plates 28 soiasito uncover more or fewer of theperforation 27, the action oi' the ventilators 13 may be controlled.

From the foregoing description and a study of the dra-Wing it Will beapparent that I have thus provided a lsimply constructed refrigeratorWhich vvillbe highly efficient in cooling action Without the employmentof ice, 'the device being consequently very economical in use.

While I have shown and described the VHaving thus described myinvention, I claim:

A. refrigerator formed as an integral hol- W body of porous material,having Va door .opening and a door therefor, Ventilating means Withinthe upper portion of the body, apen located Within the bottom-portion ofthe body and containing Water, a cover for said pan `forming the'bottomof the refrigerating space, the cover being provided at its edges withnotches and the inner surfaces of the Valls of the body beingformed withvertical .grooves registering v'vith said notchesnand having overhangingside edges, and Wicks disposed within said grooves, passing through saidnotches, and dipping into the pan.

In testimony Whereof'I affix my signature.

RUSSEL H. BREMER.
